W e theoretically and empirically investigate the relationship between information technology (IT) and firm innovation. Invoking absorptive capacity (ACAP) theory, we introduce and develop the concepts of three types of IT-enabled knowledge capabilities. Firm innovation is examined through two observable innovation outcomes: patents, and new product and service introductions. These innovation outcomes are often labeled as competitive actions aggressively undertaken by firms to gain market share or to achieve profitability. We use secondary data about IT-enabled knowledge capabilities and innovation outcomes of 110 firms. Our data results provide strong support for our main assertion that knowledge capabilities that are enhanced through the use of IT contribute to firm innovation. The study's findings suggest that the three types of IT-enabled knowledge capabilities have differential effects on firm innovation. This study substantially contributes to the information systems (IS) research, methodology, and practice in multiple ways.Key words: absorptive capacity; business value of IT; competitive impacts of IS; firm innovation; IT-enabled knowledge capability; knowledge management; strategic management of IT History: Rajiv Sabherwal, Senior Editor.

Crowdsourcing (CS) of micro tasks is a relatively new, open source work form enabled by information and communication technologies. While anecdotal evidence of its benefits abounds, our understanding of the phenomenon's societal consequences remains limited. Drawing on value sensitive design (VSD), we explore microtask CS as perceived by crowd workers, revealing their values as a means of informing the design of CS platforms. Analyzing detailed narratives of 210 crowd workers participating in Amazon's Mechanical Turk (MTurk), we uncover a set of nine values they share: access, autonomy, fairness, transparency, communication, security, accountability, making an impact, and dignity. We find that these values are implicated in four crowdsourcing structures: compensation, governance, technology, and microtask. Two contrasting perceptions-empowerment and marginalization-coexist, forming a duality of microtask CS. The study contributes to the CS and VSD literatures, heightens awareness of worker marginalization in microtask CS, and offers guidelines for improving CS practice. Specifically, we offer recommendations regarding the ethical use of crowd workers (including for academic research), and call for improving MTurk platform design for greater worker empowerment.
